We study a three-leg spin-1/2 ladder with geometrically frustrated interleg interactions. We
call this model an anisotropic triangular-strip (ATS) model. We numerically and field …

Single crystals of Cu 3 (OH) 4 SO 4 containing triple chains of S= 1/2 spins were synthesized
by a hydrothermal method. This compound is a candidate “idle-spin” system in which some …

Basic copper formate,[Cu3 (OH) 4 (HCOO) 2], was selectively prepared by hydrolysis of
formate ions in concentrated aqueous solutions of copper formate. This material exhibits a …

The investigation of a magnetic component of the heat capacity of natural samples of copper
sulfates antlerite Cu3SO4 (OH) 4 in the temperature range below 40 K and brochantite …

Abstract The spin-1/2 triple-chain magnet Cu 3 (OH) 4 SO 4 (mineral name: antlerite) is a
candidate 'idlespin'system. In order to study the phase transitions in this compound in detail …

We have studied a natural mineral Cu 3 (OH) 4 MoO 4 (mineral name: szenicsite), which is
characterized as S= 1/2 triple-chain antiferromagnet, by measurements of the magnetic …

The magnetic properties of the triple chain magnet system Cu 3 (OH) 4 SO 4 were examined
by evaluating the spin exchange constants, the Dzyaloshinskii–Moriya (DM) vectors, and the …

Abstract Cu 3 (OH) 4 MO 4, which is a natural mineral szenicsite, has been studied by the
magnetic susceptibility, the specific heat, and the high field magnetization measurement …

The heat capacity of natural chalcanthite (copper sulfate pentahydrate, CuSO 4· 5H 2 O)
from the deposit Kosmurun has been measured by the method of low-temperature adiabatic …

Using the hydrothermal synthesis method, samples of basic copper sulfates Cu3 [SO4](OH)
4 and Cu4 [SO4](OH) 6 were obtained, which showed good agreement with the natural …
